摘要
在变载荷影响下,船舶动力系统中的不锈钢钢丝绳,极易因振动波的振幅发生改变,而出现严重振荡现象。为解决上述问题,设计变载荷下船舶动力机械不锈钢钢丝绳减振装置。通过变载荷引起的激振力确定、动力机械减振控制2个步骤,完成新型减振装置应用环境的搭建。通过钢丝绳隔振器选择、船舶隔振垫设计、振荡采集传感器设计3个步骤,完成新型减振装置使用模块的搭建。控制变量因素设计对比实验结果显示,应用变载荷下船舶动力机械不锈钢钢丝绳减振装置后,振动波振幅的变化情况得到有效控制,钢丝绳严重振荡现象的发生几率,也得到一定程度的抑制。
Under the influence of variable load, the stainless steel wire rope in the marine power system is liable to vibrate due to the change of the amplitude of the vibration wave. In order to solve the above problems, we design the damping device of marine power machinery stainless steel wire rope under variable load. Through the two steps of determining the exciting force caused by the variable load and the damping control of the dynamic machinery, we can complete the building of the application environment of the new damping device. Through three steps, including wire rope isolator design, ship vibration isolation pad design and oscillation acquisition sensor design, we complete the building of new damping device module.The control variable factor design comparison experiment results show that the vibration amplitude of the vibration wave is effectively controlled and the occurrence probability of the serious oscillation of the wire rope is controlled, and a certain degree of suppression is obtained after the application of the variable load on the vibration damping device of the stainless steel wire rope under the variable load.
